4.2 Topology Optimization
The model is optimized further using the topology optimization tool, by considering mass minimization as objective function and allowable maximum stress as
response constraint. Topology optimization resulted in geometry as shown in Fig. 5
with lowest possible weight and capable of lifting an all-up weight 2 kg. Finally,
topology optimized model is verified and validated using static structural finite
element analysis.
Figure 5 shows the results of topology optimization. It is observed that the shape
is uneven and rough, which is very difficult to manufacture. Hence the design is
remodelled as shown in Fig. 6.
For validation, the remodelled geometry is analyzed with the same loading and
boundary conditions. From the results, maximum stress of 0.8 MPa and maximum
